Abstract

A touch screen that uses pressure to control the zoom ratio and the zoom area. The touch screen has a display panel, a touch sensor, and a display control. The display panel is used to display an image. The touch sensor is used to sense the position and intensity of the pressure exerted on the touch screen. The display control is connected to the display panel and the touch sensor. Pressure exerted on the touch sensor is interpreted by the display control to change the zoom area and the zoom ratio of the image on the display panel.
